Changes in IAN after SP1

Hello,I did my first flight after SP1 installation on LFMN - LOWI with Austrian OE-LNO livery. As all LOWI NGX fans know this is a place to experience an IAN approach. I noticed that something has changed in Arrival selection and Approach reference pages in the aspect of IAN. After SP1, G/S ON/OFF options in Arrival and Approach reference pages are only available when an ILS approach is selected. However this option was always available in both pages regardless of the approach method and it was like a magic switch of creating a G/P on every approach. I even remember a topic about using FMC drawn G/P on a visual approach by the help of this option. Now, I understand that it is replaced by a semi-automatic procedure which initiates IAN when an where applicable. Because my approach turned into IAN after establishing on LOC course and pushing APP. So, I just would like to be enlightened about which case is complying with the real life.Suavi Akar
